Description

[0001] The present invention relates to a ground anchor removal device designed for removing a ground anchor anchored in the ground or for removing a ground anchor from the ground. Furthermore, the ground anchor removal device can be coupled to an anchor drilling rig. Furthermore, the present invention also relates to an anchor drilling rig.

[0002] Ground anchor removal devices are known in the art. Such ground anchor removal devices are used in the art to remove ground anchors inserted into the ground. Such ground anchors are used, for example, to secure greenhouses or polytunnels in agriculture. For this purpose, the ground anchors are inserted into the ground using a ground anchor removal device and removed from the ground using a ground anchor removal device after the respective harvest season or when dismantling the polytunnels or greenhouses.

[0003] Ground anchor removal devices are comparatively complex to operate in practice and always require multiple operators to manually remove each ground anchor individually. To do this, the ground anchor removal device is moved toward the ground anchor to be removed, and then each ground anchor is removed from the ground individually.

[0004] In practice, installing ground anchors is comparatively complex, as a ground anchor insertion device is required to insert the ground anchors into the ground. A ground anchor removal device is also required to remove the ground anchors after the harvest season.

[0005] Since removing ground anchors from the ground is comparatively laborious, some farmers refrain from removing them. Alternatively, they sometimes attempt to remove the ground anchors manually, for example, by plowing the field beforehand. In this case, however, the risk of damaging the ground anchors is accepted, and it requires considerable effort to retrieve the ground anchors loosened by plowing.

[0006] Ground anchor removal and insertion devices are only needed at the beginning and end of each harvest season, so that during the rest of the season, these systems and devices are simply space-consuming or require a large amount of storage space. This also represents a disadvantage for the user.

[0007] The object of the present invention is to avoid the aforementioned disadvantages or at least to reduce them substantially.

[0008] The above object is achieved by a ground anchor unscrewing device according to claim 1.

[0009] The ground anchor removal device according to the invention is intended for removing a ground anchor anchored in the ground or for removing a ground anchor from the ground. Furthermore, the ground anchor removal device is intended for coupling to an anchor drilling rig or is connectable to an anchor drilling rig or is designed as part of the anchor drilling rig, which can also be removed if necessary.

[0010] The anchor drilling rig, in turn, can be designed to either screw in or unscrew the ground anchor. For this purpose, the anchor drilling rig can be converted and / or modified accordingly.

[0011] In particular, the ground anchor removal device according to the invention is intended for installation on a frame of the anchor drilling rig. The anchor drilling rig, which can be converted to either screwing in or screwing out, can have a frame. This frame of the anchor drilling rig can be used both when the anchor drilling rig is used for screwing in ground anchors and for unscrewing ground anchors.

[0012] Particularly preferably, the ground anchor removal device is provided for arrangement on a displacement unit connected to the frame and displaceably arranged on the frame. The displacement unit can in particular be arranged on the frame so as to be longitudinally displaceable and / or height-adjustable. The displacement unit serves in particular to selectively hold a ground anchor insertion unit of a ground anchor insertion device or a ground anchor removal unit of the ground anchor removal device. Thus, the anchor drilling rig can be equipped accordingly, particularly when used for driving in or removing ground anchors, with at least one ground anchor insertion device or at least one ground anchor removal device, wherein the relevant ground anchor insertion units or ground anchor removal units can be arranged on the displacement unit.

[0013] The ground anchor removal device comprises a ground anchor removal unit for frictionally engaging the ground anchor. In particular, the ground anchor is clamped, preferably frictionally, at its end and / or with an end region in the ground anchor removal unit.

[0014] The aforementioned connection of the ground anchor to the ground anchor removal unit can ensure the transmission of torque from the ground anchor removal unit to the ground anchor when the ground anchor is removed from the ground and thus in particular lead to a pulling movement of the ground anchor out of the ground.

[0015] It is understood that the ground anchor can be removed from the ground in particular in such a way that it can be pulled and rotated at the same time.

[0016] The advantage of the ground anchor removal device according to the invention can be seen in the fact that it can be arranged on existing anchor drilling rigs, in particular as a “retrofit option”.

[0017] Particularly preferably, the ground anchor removal device can be mounted on existing anchor drilling rigs used in the field for driving in ground anchors, preferably as a replacement for the ground anchor removal unit. This allows the user to economically utilize the anchor drilling rig for selectively driving in and removing ground anchors.

[0018] According to the invention, the anchor drilling rig can thus be used simultaneously for (ground) anchor driving or, after appropriate conversion, for (ground) anchor removal. This is particularly advantageous because it eliminates the need to maintain separate systems for anchor removal and anchor driving.

[0019] The anchor drilling system can be converted, for example, by replacing the ground anchor screwing devices with the ground anchor unscrewing devices or vice versa.

[0020] The anchor drilling system comprises at least one ground anchor screwing device and at least one ground anchor unscrewing device, although both devices do not have to be arranged on the frame when the anchor drilling system is in use, but can be arranged.

[0021] If the anchor drilling rig is used, for example, for (ground) anchor removal, the ground anchor removal device(s) is / are preferably arranged on the frame, and the ground anchor insertion device(s) is / are stored separately. If the anchor drilling rig is to be used for ground anchor insertion, then the ground anchor insertion device(s) is / are preferably arranged on the frame, and the ground anchor removal device(s) is / are preferably stored separately. In principle, it can also be provided that both the ground anchor removal device(s) and the ground anchor insertion device(s) are arranged on the frame of the anchor drilling rig, and that one of the devices is / are used optionally.

[0022] Accordingly, the invention provides an efficient, economical and space-saving system for screwing in and out ground anchors.

[0023] In a particularly preferred embodiment of the invention, the ground anchor removal device comprises a drive unit for driving the ground anchor removal unit such that the ground anchor is rotated and simultaneously pulled for removal from the ground. The drive unit can, in particular, also be arranged at least indirectly on the displacement unit and, in particular, interact with the ground anchor removal unit of the ground anchor removal device. In this case, the drive unit can, in particular, transmit a torque to the ground anchor removal unit, which in turn can transmit the torque to the ground anchor sunk into the ground, causing it to rotate.

[0024] In addition to rotating the ground anchor, the drive unit can also be designed to pull the ground anchor out of the ground. For this purpose, the ground anchor removal unit can be mounted on the frame in a height-adjustable or height-sliding manner, particularly via the preferably height-adjustable sliding unit, so that the ground anchor can also be pulled out of the ground by "pulling" the ground anchor removal unit upward.

[0025] In particular, the drive unit can be designed such that the ground anchor is only rotated and / or pulled when the ground anchor is (still) in contact with the ground. This particularly increases work safety, ensuring that the ground anchor is only moved when it is still in the ground. If necessary, this can also be omitted, since external operating personnel in particular can preferably arrange the ground anchor removal unit on the ground anchor in such a way that rotation is only initiated when the ground anchor unit is firmly connected to the ground anchor for torque transmission. As soon as the ground anchor has been removed from the ground, rotation of the ground anchor removal unit can then be stopped, in particular immediately, preferably by external operating personnel.

[0026] Furthermore, in a further preferred embodiment, the ground anchor removal unit comprises a connecting means for receiving the ground anchor at least at the end and / or in certain regions and for frictionally clamping the ground anchor. In particular, the ground anchor is clamped at the end in the connecting means, preferably so that the torque can be transmitted from the ground anchor removal unit to the ground anchor. The relevant coupling between the drive motor and the ground anchor can then be ensured, among other things, by the connecting means.

[0027] In addition, the connecting means enables the ground anchor to be connected to the ground anchor removal unit in a simple and quick manner—in particular by means of tensioning and / or by means of a frictional and / or positive connection. To ensure a secure connection, it can be provided that the connecting means can be arranged at least partially around the end region of the ground anchor, in particular the front end region of the ground anchor. For this purpose, the connecting means can in particular have four side walls, which preferably surround the ground anchor, which in particular has a circular cross-section at least in sections, in the closed state.

[0028] The connecting device can preferably be attached to the ground anchor and then connected to the ground anchor.

[0029] Preferably, the connecting means can be folded open at least in some areas. In particular, the connecting means can be designed such that two elements of the connecting means can be opened or folded open, in particular relative to one another. In particular, the connecting means has a quick-release fastener for closing the connecting means in the folded position. The quick-release fastener can, in particular, have a tensioning strap with a locking hook. Alternatively or additionally, the quick-release fastener can also have a lever lock with a corresponding counterpart for easy opening and closing of the connecting means.

[0030] In a further, also preferred embodiment, the quick-release fastener can also be spring-loaded and / or have a spring lock.

[0031] Ultimately, the quick-release fastener allows for easy opening and closing at the location where the ground anchor has been inserted into the ground. In practice, connecting to the ground anchor should preferably be as quick as possible to efficiently remove the ground anchors from the ground across the entire field. A quick-release fastener offers a particularly useful option here, enabling quick and easy connection and disconnection.

[0032] The quick-release fastener can be arranged on at least one of the side walls, in particular on two side walls or on an upper side and preferably at least one side wall. The movement for closing the quick-release fastener can therefore be at least substantially horizontal or at least substantially vertical relative to the floor. A vertical closing movement of the quick-release fastener enables, in particular, simple operation and preferably safe accident prevention, in particular in compliance with accident prevention regulations (UVV).

[0033] In particular, the connecting means has a limiter for restricting the opening angle of the connecting means. The limiter can preferably be designed as a stop for the quick-release fastener. This ensures that the quick-release fastener in particular cannot be opened completely and the opening angle of the connecting means can ultimately be limited. This is particularly useful because it ensures that the connecting means does not undesirably open completely when arranged on the ground anchor, but in particular gives the user just enough play to couple the connecting means to the ground anchor in a comparatively simple manner. Preferably, the connecting means can only be opened and closed over the limited opening angle. The limiter also ensures simplified use of the connecting means.

[0034] In a further preferred embodiment of the inventive concept, it is provided that the connecting means is arranged in an articulated manner on a holding unit of the ground anchor removal device. In particular, the holding unit can be firmly connected to the displacement unit of the anchor drilling rig. The articulated mounting can make it possible for the connecting means not to be arranged in alignment or on an axis with the ground anchor, but rather within a predetermined radius in order to be coupled to the ground anchor. In particular, the ground anchor can be arranged at a maximum distance of at least 10 cm, preferably at least 15 cm, from the rest position of the connecting means. This results in a so-called "search area" around the position of the inserted ground anchor.

[0035] Preferably, the holding unit can be height-adjustable together with the displacement unit during use of the anchor drilling rig.

[0036] If necessary, the holding unit can also be arranged on the frame together with the displacement unit so that it can be moved longitudinally. Longitudinal displacement of the displacement unit and the holding unit can be performed, in particular, before use of the anchor drilling rig. The height of the holding unit can be adjusted together with the displacement unit, particularly during use, especially when the ground anchor is pulled out of the ground, since this increases the distance between the ground and the holding unit, and thus the holding unit is preferably arranged on the frame of the anchor drilling rig so that it can be adjusted in height.

[0037] Particularly preferably, the holding unit comprises a holding strut that is oriented at least substantially vertically relative to the ground. The holding strut can be arranged or oriented at least substantially in the longitudinal direction of the ground anchor, with the ground anchor being inserted into the ground, in particular, vertically relative to the ground surface.

[0038] In particular, the drive unit and / or a motor of the drive unit can preferably be mounted directly, and the ground anchor removal unit can be mounted at least indirectly, in a receptacle of the holding unit. In particular, a motor is arranged in this receptacle. The receptacle preferably has a bottom facing the ground and / or at least one, in particular two, side wall(s) for arranging the motor.

[0039] The mount can, in particular, be arranged on the support strut in a height-adjustable manner, allowing the distance between the drive motor and the floor to be varied. The height of the mount is adjusted, in particular, before use of the system and preferably not during operation. This allows the mount to move, in particular, together with the support unit and the support strut.

[0040] A cardan shaft of the ground anchor removal unit can be provided for the articulated mounting of the connecting means. The cardan shaft can, in particular, enable the aforementioned search area for the ground anchor. Thus, in particular, the ground anchor can be arranged at a maximum distance of at least 10 cm, preferably at least 15 cm, from the longitudinal axis of the cardan shaft in the rest position, in particular wherein the cardan shaft can be moved in different directions, which can preferably result in a maximum diameter of the search area, within which the ground anchor can be arranged, of at least 20 cm, preferably of at least 30 cm.

[0041] In particular, the propeller shaft can have a ball joint at each end or face. The propeller shaft can then be connected in an articulated manner, in particular via at least one ball joint, to the connecting means and / or the mount and / or the motor. Most preferably, the propeller shaft has two ball joints, with one ball joint being coupled to the motor and another ball joint being coupled to the connecting means, at least indirectly, in particular directly.

[0042] For coupling to the ball joint, connecting pins can be provided. Thus, a connecting pin that can be coupled to the propeller shaft, preferably arranged on an upper side of the connecting means, can be provided for arrangement on the propeller shaft and / or on the ball joint of the propeller shaft. Alternatively or additionally, a further connecting pin can be provided for at least indirect arrangement on the motor, wherein the further connecting pin, which is assigned to the motor, can also be connected to the ball joint.

[0043] In a further preferred embodiment, the connecting means has a hinge for folding out. In particular, the hinge is arranged between two clamping elements of the connecting means for clamping the ground anchor. The hinge can then ensure that the two, in particular rigid, clamping elements can be folded out relative to one another. In particular, at least one clamping element can have at least one preferably replaceable jaw chuck for clamping the ground anchor. In particular, each clamping element preferably has at least one jaw chuck. Particularly preferably, each clamping element has two side walls, in particular arranged at least substantially at right angles to one another, wherein each side wall is preferably assigned an inner, in particular replaceable, jaw chuck. Accordingly, particularly preferably four jaw chucks are provided per connecting means.The ground anchor can then be gripped and / or clamped between the jaw chucks. A particular advantage of the jaw chucks is that they can be interchanged. If, for example, ground anchors with a different diameter are used, the jaw chuck can be adjusted to the corresponding outer diameter of the ground anchor. This means that the ground anchor removal unit can also be used for ground anchors with different outer dimensions.

[0044] The connecting means particularly preferably has an upper side, which can in particular be coupled to the cardan shaft, with at least one upper-side through-opening for checking the arrangement of the ground anchor in the connecting means. The through-opening can therefore also be referred to as a viewing window of the connecting means. The upper side borders in particular on the side walls of the connecting means. Opposite the upper side can in particular be the end face of the connecting means through which the ground anchor is guided, at least in part, for bracing in the connecting means. The through-opening thus enables operating personnel to check whether the ground anchor is optimally arranged in the connecting means. This check also ensures that the jaw chucks also lie directly against the outer diameter of the ground anchor and thus clamp the ground anchor preferentially.

[0045] As explained above, a connecting pin can preferably also be provided on the upper side of the connecting means for arrangement on the cardan shaft, in particular the ball joint of the cardan shaft, and / or for at least indirect arrangement on the engine.

[0046] In a further preferred embodiment, the drive unit has a hydraulic motor and a hydraulic control unit. Accordingly, the ground anchor removal unit can in particular be operated hydraulically. The hydraulic motor can preferably also be designed to selectively drive the ground anchor insertion unit. Accordingly, the drive motor can be assigned to either the ground anchor removal unit or the ground anchor insertion unit, so that different drive motors do not have to be provided for the ground anchor removal unit and the ground anchor insertion unit. According to the invention, the motor can also be referred to as the drive motor or vice versa. A hydraulic drive of the ground anchor removal unit enables in particular continuous, low-wear and maintenance-friendly operation and, in particular, a wear-resistant design of the entire ground anchor removal device.

[0047] As explained above, the motor of the drive unit can preferably have a further connecting pin for connection to the cardan shaft, in particular to the further ball joint of the cardan shaft. Thus, the motor can be coupled, in particular indirectly, to the cardan shaft and thus to the connecting means via the connecting pin.

[0048] Particularly preferably, the hydraulic control unit is also designed to drive the hydraulic motor for the ground anchor screwing unit. The hydraulic unit can preferably be switchable between operation for the ground anchor removal unit and the ground anchor screwing unit. In particular, switching between operations requires a change in the flow direction of the hydraulic fluid. A manual switch can be provided for switching. In a further alternative, likewise preferred embodiment, the hydraulic control unit can also be electronically actuated. In this case, switching via manual intervention by an operator via a hand switch or lever can be omitted.

[0049] Accordingly, the hydraulic unit can preferably be operated manually and / or electronically. Electronic actuation of the hydraulic control unit is particularly preferred, in particular since it can then be operated with as little susceptibility to errors as possible. However, with appropriate training of the specialist personnel, manual operation of a hydraulic control unit, which is preferably designed to drive both the ground anchor removal unit and the ground anchor insertion unit, can also be carried out. Alternatively or additionally, it can also be provided that different hydraulic control units are provided for the ground anchor removal unit and the ground anchor insertion unit, so that in particular switching when using the ground anchor insertion device and the ground anchor removal device can be omitted.

[0050] Furthermore, the present invention relates to an anchor drilling system for selectively screwing in or unscrewing at least one ground anchor from or into the ground according to claim 9.

[0051] The anchor drilling system according to the invention has at least one ground anchor unscrewing device according to one of the aforementioned embodiments and at least one ground anchor screwing device for screwing in the ground anchor.

[0052] Furthermore, the anchor drilling system comprises a frame and at least one displacement unit displaceably arranged on the frame for the respective selective mounting of a ground anchor screwing unit of the ground anchor screwing device or a ground anchor unscrewing unit of the ground anchor unscrewing device.

[0053] In a further preferred embodiment, the displacement unit can hold both the ground anchor insertion unit and the ground anchor removal unit. The anchor drilling system can therefore preferably be equipped with either the ground anchor removal device or the ground anchor insertion unit, or with both the ground anchor removal device and the ground anchor insertion unit. All of the aforementioned embodiments are possible in principle.

[0054] The displacement unit can, in particular, be arranged on the frame so as to be longitudinally displaceable and height-adjustable. A longitudinal displacement of the displacement unit occurs, in particular, before use of the anchor drilling system, in particular depending on the position of the ground anchors. The anchor drilling system preferably has two ground anchor removal devices or two ground anchor insertion devices, which are arranged, in particular, at least substantially the same distance from the center of the frame. Accordingly, the anchor drilling system can, in particular, simultaneously screw in or unscrew two ground anchors.

[0055] Preferably, the anchor drilling system also comprises a drive unit for selectively driving the ground anchor removal unit or the ground anchor insertion unit.

[0056] Accordingly, either several drive units can be provided for the ground anchor removal unit and the ground anchor insertion unit, or one drive unit can be provided that selectively drives the ground anchor removal unit or the ground anchor insertion unit.

[0057] It is understood that all of the aforementioned embodiments and / or advantages and / or preferred features of the ground anchor removal unit can equally apply to the anchor drilling system without requiring any further explanation. Likewise, the statements regarding the anchor drilling system can also be applied to the ground anchor removal device without requiring any further explicit explanation.

[0058] The anchor drilling rig according to the invention is characterized by the fact that, particularly after appropriate conversion, it can be used either for screwing in or removing ground anchors. Accordingly, a single rig can be used to insert and remove the ground anchors from the ground. The prior art only describes different rigs that can either screw the ground anchor into the ground or remove it from the ground. The invention provides the advantage that different rigs for ground anchoring via ground anchors do not need to be maintained.

[0059] A further advantage is that when using the anchor drilling system for anchor removal, the exact distances between the anchor drills can be maintained that were also specified for ground anchor insertion. Accordingly, a ground anchor removal device or ground anchor insertion device can be arranged, particularly at the respective front end areas of the frame. The distance between these devices then also indicates the distance between the ground anchors. This distance can then also be preferably maintained when removing the ground anchors.

[0060] In a particularly preferred embodiment, the drive unit is configured to drive the ground anchor removal unit such that the ground anchor is pulled out of the ground and simultaneously rotated. Preferably, the ground anchor is only rotated and / or pulled when the ground anchor is in contact with the ground or is still located in the ground. This serves to increase work safety. Alternatively, the ground anchor or the drive unit can also be rotated during the entire driving process, especially when the ground anchor is outside the ground.

[0061] Alternatively or additionally, the drive unit can be configured to drive the ground anchor screwing unit in such a way that the ground anchor is pushed into the ground and simultaneously rotated, whereby, preferably, the ground anchor is only rotated once the ground anchor has contact with the ground. This also increases work safety.

[0062] As explained above, two ground anchor unscrewing devices or at least two ground anchor screwing devices can preferably be arranged on the frame. In particular, the respective devices are arranged on the front end regions of the frame. In particular, each ground anchor screwing device and each ground anchor unscrewing device is assigned a displacement unit, wherein, preferably, each ground anchor screwing unit or each ground anchor unscrewing unit is arranged on the frame so as to be displaceable, in particular longitudinally displaceable and / or height-adjustable, via the respective displacement unit. The displacement unit adjusts its height (i.e. distance from the ground) in particular when the ground anchor is pressed into the ground or pulled out of the ground, which also causes a change in the height of the displacement unit and consequently of the respective ground anchor devices (i.e. ground anchor unscrewing device or ground anchor screwing device).

[0063] Accordingly, the sliding unit is particularly preferably arranged on the frame so that it is height-adjustable and longitudinally displaceable.

[0064] In a further preferred embodiment, a holding unit of the ground anchor removal device is arranged on the displacement unit, in particular wherein the holding unit is firmly connected to the displacement unit of the anchor drilling rig. Alternatively or additionally, it can be provided that the holding unit has a holding strut that is aligned, in particular, substantially vertically to the ground. The holding strut can then be displaced, in particular, relative to the displacement unit. In addition, the holding unit can also be designed to hold the ground anchor insertion device.

[0065] Furthermore, in a further preferred embodiment of the inventive concept, it is provided that when using the anchor drilling system for removing ground anchors, the motor is preferably arranged or mounted directly and the ground anchor removal unit is arranged or mounted at least indirectly on a receptacle of the holding unit, wherein, preferably, the receptacle is arranged fixedly and preferably displaceably on the holding strut.

[0066] Alternatively or additionally, it can be provided that when using the anchor drilling system for screwing in ground anchors, the motor is preferably mounted directly and the ground anchor unscrewing unit is mounted at least indirectly on a receptacle of the holding unit, wherein, preferably, the receptacle is arranged fixedly and preferably displaceably on the holding strut.

[0067] Particularly preferably, the receptacle can serve to accommodate the motor, which is coupled either to the ground anchor removal unit or the ground anchor insertion unit and can thus be used to drive either the ground anchor removal device or the ground anchor insertion device, in particular thereby eliminating the need to maintain different drive motors. However, different drive motors can also be used if necessary.

[0068] In a particularly preferred embodiment, at least one support is provided on the frame for support on the floor. The support can be designed, in particular, as a skid. Particularly preferably, several supports are provided across the width of the frame. The supports can be arranged on the frame in a height-adjustable manner and thus adapt, in particular, to uneven floors.

[0069] It is also particularly preferred that the frame be designed to be collapsible. This enables, in particular, transport of the anchor drilling rig along regular transport routes, such as roads or the like. This also allows for space-saving storage of the anchor drilling rig, for example, in a barn on a farm or the like. In particular, the frame can have at least two collapsible frame sections. The frame sections can be collapsible, in particular, via a hinge or the like.

[0070] Particularly preferably, the anchor drilling rig is designed to be mobile. For this purpose, the anchor drilling rig can, in particular, have wheels and / or a chassis for movement. Particularly preferably, the anchor drilling rig is movable and / or can be coupled to a vehicle. Accordingly, the anchor drilling rig can be used either as a rear attachment or as a front attachment of an agricultural vehicle. Moving the anchor drilling rig makes it possible to remove the ground anchors, which can be distributed across an entire field, from across the entire field, thus ensuring an efficient process for screwing in and out the ground anchors.

[0071] Furthermore, it is expressly pointed out that all the intervals mentioned above and below include all intermediate intervals and individual values ​​contained therein and that these intermediate intervals and individual values ​​are to be regarded as essential to the invention, even if these intermediate intervals or individual values ​​are not specifically specified in detail.

[0072] Further features, advantages and possible applications of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawing and the drawing itself. All described and / or illustrated features, individually or in any combination, form the subject matter of the present invention, regardless of their summary in the claims or their reference back to them.

[0074] Fig. 1 shows an anchor drilling rig 1 with ground anchor removal devices 2 arranged thereon. The anchor drilling rig 1 has a frame 5. The ground anchor removal devices 2 are arranged on the frame 5, in particular height-adjustable and / or at least partially longitudinally displaceable. Fig. The ground anchor unscrewing devices 2 shown in Figure 1 are intended for unscrewing a ground anchor 4 anchored in the ground. The ground anchor 4 is also in Fig. 1, but is also Fig. 3 can be seen.

[0075] It is understood that in further preferred embodiments, only one ground anchor removal device 2 may be provided for an anchor drilling rig 1. Finally, the ground anchor removal device 2 is provided for coupling to an anchor drilling rig 1, which is designed for selectively screwing in or unscrewing the ground anchor 4. Fig. 1 merely shows that the anchor drilling rig 1 is designed to unscrew the ground anchor 4 using the ground anchor unscrewing devices 2. The anchor drilling rig 1 can, by appropriate conversion, also be designed, in particular, to screw in the ground anchor 4. For this purpose, the ground anchor screwing devices 3 can be arranged on the anchor drilling rig 1, in particular by exchanging the ground anchor unscrewing devices 2 with the ground anchor screwing devices 3 and / or by arranging / arranging the ground anchor screwing devices 3 on the frame 5 in addition to the ground anchor unscrewing devices 2.

[0076] The Fig. Figure 2 shows an anchor drilling rig 1 having ground anchor driving devices 3 for driving ground anchors 4 into the ground. It is understood that the anchor drilling rig 1 may also have only one ground anchor driving device 3. The ground anchor driving devices 3 may also be arranged on the frame 5, in particular in a height-adjustable and / or longitudinally displaceable manner.

[0077] Fig. 1 also shows that a displacement unit 6 - in the illustrated embodiment, two displacement units 6 - is arranged on the frame 5. The displacement unit 6 can, in particular, be arranged displaceably on the frame 5, in particular height-adjustable and / or longitudinally displaceable. The displacement unit 6 is connected to the frame 5. The displacement unit 6 can be designed to selectively hold a ground anchor insertion unit 7 of a ground anchor insertion device 3 or a ground anchor removal unit 8 of the ground anchor removal device 2. The Fig. 1 and Fig. 2 show in this context that either ground anchor screwing devices 2 or ground anchor unscrewing devices 3 are arranged on the displacement units 6. It is understood that the anchor drilling rig 1 can have at least one displacement unit 6.

[0078] Furthermore, the Fig. 1, that a ground anchor removal unit 2 is provided for frictionally engaging, in particular clamped, connection with the ground anchor 4. In particular, the ground anchor 4 can be clamped to the ground anchor removal unit 8.

[0079] A drive unit 9 of the ground anchor removal device 2 can be designed to drive the ground anchor removal unit 8 in such a way that the ground anchor 4 is rotated and simultaneously pulled for removal from the ground.

[0080] The drive unit 9 can optionally also be designed to drive the ground anchor screwing device 3.

[0081] In particular, the drive unit 9 enables a torque to be transmitted to the ground anchor removal unit 8, which in turn can transmit the torque to the ground anchor 4. It is understood that the drive unit 9 can be designed such that the torque can be transmitted to the ground anchor 4, in particular via the ground anchor removal unit 8.

[0082] The ground anchor 4 can be pulled out of the ground by the drive unit 9 being simultaneously designed to adjust the height (i.e., its distance from the ground) of the ground anchor removal unit 8. In particular, the drive unit 9 can be designed to adjust the height (i.e., its distance from the ground) of the displacement unit 6, on which the ground anchor removal device 2 can be arranged. In particular, the displacement unit 6 can be pulled upwards to remove the ground anchor 4, whereby the ground anchor removal unit 8 can also be pulled upwards.
